If you’re working with a legacy React codebase, then this course will prove useful. React has seen a great deal of change over the years, but there might be situations where you have to work with an older version.

In this course, you will learn the fundamentals of V15 React. You will learn how to work with an API, how to organize and test your code as well as how to give your React app state. Throughout this course, you will have hands-on experience building a fully functional Hacker News App. By the end of this course, you will be prepared to build your own applications and have something to showcase in your portfolio.

If you’re looking for the updated version of this course featuring V16, please visit The Road to React: The one with Hooks.

I’m doing Robin’s Road to Learn React course this weekend & I almost feel guilty for having so much fun.

The Road to learn React by Robin Wieruch is a must read. Clean and concise for React and JavaScript.

This is one of the most well-written & informative coding books I’ve ever worked through. A solid React & ES6 introduction.

The Road to Learn React by Robin Wieruch is such an awesome book! Most of what I learned about React and even ES6 was through it!

I recommend this to any student or professional interested in learning react basics to advanced level. I have 17 years of experience in web and desktop app development, and before reading this I was having trouble in learning react. It works like magic.

The Road to React: The One with Class Components

JavaScript ES6 introduced classes, which are commonly used in object-oriented programming languages. JavaScript, always flexible in its programming paradigms, allows functional programming and object-oriented programming to work side-by-side.

While React embraces functional programming, e.g. immutable data structures and function compositions, classes are used to declare ES6 class components. React mixes the good parts of both programming paradigms.

Consider the following Developer class to examine a JavaScript ES6 class without a component.

class Developer {
  constructor(firstname, lastname) {
    this.firstname = firstname;
    this.lastname = lastname;
  }

  getName() {
    return this.firstname + ' ' + this.lastname;
  }
}

A class has a constructor to make it instantiable. The constructor takes arguments and assigns them to the class instance. A class can also define functions. Because the function is associated with a class, it is called a method, or a class method.

The Developer class is only the class declaration we use here, as you can create multiple instances of a class by invoking it. It is similar to the ES6 class component, which has a declaration, but you have to use it somewhere else to instantiate it:
